This invention can be used in nanophotonics, telecommunication, all-optical computing, and quantum computing.
All optical signal processing requires devices that are ultrafast and operate at telecommunication power levels. There is a need for optical devices that can fulfill the requirements in size, switching time and operating power of practical integrated optical systems.
This invention utilizes a solid-state-based electromagnetically induced transparency (EIT) as the non-linear medium in photonic crystal cavities. This increases the non-linear properties of the photonic crystal because EIT is a superb non-linear medium and photonic crystal cavities are optimal structures with respect to maximizing non-linear effects. Consequently, optical devices designed with this process has unprecedented non-linear sensitivity, with operating power requirements many orders of magnitude smaller than in most non-linear optics devices.
Improved the performance of nonlinear optical devices such that the corresponding operation powers and switching times are suitable for implementation in realistic, ultrafast integrated optical devices
Enables the miniaturization of optical devices without affecting the operating power requirements
